After a few hours of intensive playing, I pronounce this operation...a success!
The VHII bridge sounds HUGE in the neck spot, to the extent that I had to lower it a fair bit so as not to overwhelm the C-Pig volume-wise. In terms of tone, it's nicely balanced across the EQ spectrum, with plenty of mids to induce singing sustain--not something that can be said of all A5 neck 'buckers. The highs remain crystal clear under heavy overdrive, so the sounds cuts through easily, and the lows are impressively tight. The attack is also crisp and pronounced, making it well suited to fast alternate picking.
I'm not sure I'd use it for classic rock or ultra-clean tones, but as a loud, proud soloing machine for hard rock and metal, it will do the job very nicely. Just be sure to pair it with something hot!
